By the way, president No. 44 makes a brilliant cameo in 42's big rendition around the 0:25-second mark (the bit's swiped from POTUS' acclaimed version of Al Green's "Let Stay Together" at a campaign fundraiser in New York last year).

For a prez who's sometimes knocked for being longwinded, Clinton is pretty darn crisp here with his take on Thicke's ubiquitous hit, though without Robin's signature falsetto.

The only other thing missing is some backup from PharrellWilliams and, well, maybe the dancing girls that grace Thicke's original music video.

So far Barackdubs' latest offering has racked up some 262,000 views as of press time.

But it's not the first occasion that "Blurred Lines," which has racked up 105 million views on YouTube, has gotten the mash-up treatment.

Other notable mash-ups include "Blurring Pains," mixing the song with the "Growing Pains" theme; "Blurred Lines as Cosby Show Theme," in which the tune plays over the classic comedy's opening credits; and most notably Jimmy Kimmel's parody last month.
